Brand note

Some By Mi is a Korean skincare brand that centers on exfoliation for acne-prone and textured skin, with its AHA BHA PHA 30 Days Miracle Toner as the clear anchor. The toner combines three acids to smooth skin, reduce sebaceous filaments, and clear closed comedones without irritating sensitive skin, according to creators. It's lightweight and hydrating, but best used as a treatment 2-3 times per week rather than daily, since overuse can cause irritation.
